Description

Technical Field

[0001] The present invention relates to the field of tooling, and more particularly to an automatically switchable flexible tooling for bumper assembly. Background Art

[0002] At present, most of the assembly tools for automobile bumpers are special tools, that is, one tool can only complete the assembly work of a specific product and cannot be used for the assembly of multiple products at the same time. When multiple products are produced at the same time, multiple special tools corresponding to each product need to be manufactured, and the special tools will be scrapped after the life cycle of this specific product ends.

[0003] The above situation has resulted in problems such as large area occupied by special tooling, high tooling development costs, and low resource utilization. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatically switchable flexible tooling for bumper assembly, thereby solving the problems in the prior art of large occupied area of special tooling, high tooling development cost and low resource utilization.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] Provided is a flexible tooling for bumper assembly that can be switched automatically, comprising: a horizontally arranged frame; a plurality of support shafts horizontally fixed to the frame via bearing seats, the plurality of support shafts being arranged parallel to each other and spaced apart, a plurality of fixing blocks being installed through each of the support shafts; a support block fixed to the fixing block by bolts, for bumper installation; wherein the ends on the same side of the plurality of support shafts are simultaneously connected to a power rod via a connecting rod, the power rod extending perpendicularly to the support shaft, and under the action of a linear motor, the power rod drives the support shaft to rotate via the connecting rod, thereby realizing the rotation of the support block, thereby realizing automatic switching of the flexible tooling.

[0007] The fixing block is capable of translating on the supporting shaft.

[0008] At least one side surface of the fixing block is provided with a mounting hole to facilitate the installation of the supporting block.

[0009] The supporting shaft is connected to the connecting rod through a shaft hole.

[0010] The mounting surface of the power rod is provided with a plurality of bosses arranged at intervals, and the power rod is connected with the connecting rod shaft hole through the bosses.

[0011] Each supporting shaft is fixed by at least two bearing seats.

[0012] Preferably, the frame has a plurality of openings to avoid the fixing block and the supporting block.

[0013] According to the present invention, an automatically switchable flexible tooling for bumper assembly can effectively realize flexible support during the assembly process of automobile bumpers of different shapes through the ingenious design of components such as power rods, connecting rods, support shafts, fixed blocks, and support blocks, thereby realizing the function of assembling multiple products with one tooling, saving floor space, and extending the life cycle of the tooling.
